Phase 7: nine runnable examples/ programs (parse, failover chains with trailing alias, tiers, LLM_* env providers, multimodal, tool loop, Generate[T], agent, skills); docs/mort-migration.md mapping mort's go-llm/go-agentkit usage onto majordomo APIs with the planned additive library extensions and conversion order; README finalized with the complete matrix.
